    摘要: A method and apparatus for reading data from a non-volatile memory cell. In some embodiments, a cross-point array of non-volatile memory cells is arranged into rows and columns that are each controlled by a line driver. A read circuit is provided that is capable of reading a logical state of a predetermined memory cell by differentiating a non-integrated first reference value from a non-integrated second reference value. Further, each reference value is measured immediately after configuring the column corresponding to the predetermined memory cell to produce a first and second amount of current.

    摘要: Various embodiments of the present invention are generally directed to a method and apparatus for providing different bit set modes for a resistive sense memory (RSM) array, such as a spin-torque transfer random access memory (STRAM) or resistive random access memory (RRAM) array. In accordance with some embodiments, a group of RSM cells in a non-volatile semiconductor memory array is identified for application of a bit set operation. A bit set value is selected from a plurality of bit set values each separately writable to the RSM cells to place said cells in a selected resistive state. The selected bit set value is thereafter written to at least a portion of the RSM cells in the identified group.
